What is PDF

The Portable Document Format (PDF) is the file format created by Adobe Systems in 1993 for document exchange. PDF is a fixed-layout format used for representing two-dimensional documents in a manner independent of the application software, hardware, and operating system. Each PDF file encapsulates a complete description of a 2-D document (and, with Acrobat 3-D, embedded 3-D documents) that includes the text, fonts, images, and 2-D vector graphics that compose the documents.

File Extension BIN

The .BIN/.CUE image file format was developed by Jeff Arnold for the CDRWIN program. An image consists of two files which contain binary data and metadata, respectively. The filenames typically match (e.g. image.bin and image.cue). The .BIN file contains an exact copy of all data stored on an optical disc in raw, unprocessed form but without any subchannel data. For this reason, some programs use the .RAW suffix for these files.

File Extension XLS

XLS is a proprietary binary file format called Binary Interchange File Format (BIFF) as its primary format used by Excel to store spreadsheet information. Excel 2007 uses Office Open XML as its primary file format, an XML-based container similar in design to XML-based format called XML Spreadsheet (XMLSS), first introduced in Excel 2002.

File Extension TMP

MPEG-4 Part 14, formally ISO/IEC 14496-14:2003, is a multimedia container format standard specified as a part of MPEG-4. It is most commonly used to store digital audio and digital video streams, especially those defined by MPEG, but can also be used to store other data such as subtitles and still images. Like most modern container formats, MPEG-4 Part 14 allows streaming over the Internet. The official filename extension for MPEG-4 Part 14 files is .mp4, thus the container format is often referred to simply as MP4.

BUP File Extension

BUP (Back UP) is the filename extension of some files stored on video DVDs. The BUP file is a backup of the IFO file on a DVD, which contains the information about the organization of tracks, menus, chapters, subtitles on the disc. The BUP files are used in the event that the corresponding IFO file is unreadable, perhaps due to a scratch on the surface of the disc.
